That's not at all surprising, though, that's how journalism has always worked (protecting one's sources). I certainly trust the WSJ over anything that comes out of Musk's mouth, especially after those pedo accusations.
The pedo thing was a stupid mistake stemming from anger that got lit up by accusations by someone criticizing what Elon probably perceived as sincere offer of help, and he says to have later apologized.
